Answer:

1. -25

2. 2.1

Step-by-step explanation:

-1/2(x + 5) = 10

divide both sides by 2.

-1(x + 5) = 20

-(x + 5) = 20

-x = 20 + 5

x = -25

k/3.5 + 7.4 = 8

2k/7 +37/5 = 8

10k = 280 - 259

10k = 21

k = 21/10 (2.1)

Answer:

1.x=15

2.k=2.1

Step-by-step explanation:

1.-1/2(x+5)=-10

 -x+5/2=-10 multiply both sides by 2

  -x-5=-10

  -x=-20+5

 -x=-15 multiply both sides by -1

  x=15

2.k/3.5+7.4=8

 k/3.5=8-7.4

  k/3.5=0.6

 multiply both sides by 3.5

  k=2.1

Question: On this dartboard, the circle with 1-m radius is inscribed in an equilateral triangle. Find the probability that a dart that hits the board lands in the circular region. Justify your answer.

Let's start by finding the length of one of the sides of the equilateral triangle. We can do this by creating a 30-60-90 triangle from the radius of the inscribed circle.

I attached an image of what this should look like.

Solving for the length of half of the base of the equilateral triangle gives us 1√3. To get the length of the entire base of the triangle, we will double this value:

The area of an equilateral triangle is [tex]\displaystyle A=\frac{s^2 \sqrt{3} }{4}[/tex].

We can substitute the known value of s (side length) into the formula and solve for A.

The area of the equilateral triangle is 3√3.

Now, let's solve for the area of the inscribed circle. The formula for the area of a circle is [tex]\displaystyle A= \pi r^2[/tex].

We know the radius of the circle is 1, so let's substitute 1 for r:

The area of the inscribed circle is π.

To find the probability of the dart hitting a specific area on the dartboard, we will divide the desired area by the total area of the dartboard.

The probability that a dart that hits the board lands in the circular region is about 60.46%.

Answer:

  7. D: (-∞, ∞); R: [3, ∞); see attached for a graph (red)

  8. a=0; see attached for a graph

Step-by-step explanation:

7. The function is a polynomial, so its domain is all real numbers.

The parabola opens upward. It has a minimum value of 3. The range is y ≥ 3.

__

8. Putting the given point coordinates in the equation, we can solve for a.

  f(7) = 6

  6 = a(7 -5)² +6

  0 = a(2²)

  0 = a

The value of a is zero.

(The given point has the same y-value as the vertex, but is not the vertex. The function can only go through that point if it is a horizontal line (not a parabola).) The attachment shows a graph.

Answer:

90+42+x = 180

132+x=180

x=180-132

x=48

Answer:

48 DEGREES

Step-by-step explanation:

First you need to find the other two angles : 42 + 90 = 132 ( the 90 comes from the little square like shape on the other angle).

So x = 180 - 132 = 48 ( we use 180 because it is the sum of interior angles of a triangle.

Answer:

9.42

Step-by-step explanation:

Hey There!

The first step of this problem is to find the formula for arc length

[tex]arc-length=2\pi r(\frac{0}{360} )[/tex]

r=raduis

0 = angle

now we just plug in the values

[tex]arc-length=2\pi 10\frac{54}{360} \\2\pi =6.283185307\\6.283185307x10=62.83185307\\62.83185307\frac{54}{360}=9.424777961[/tex]

so the arc length equals 9.424777961

the last step is to round to the nearest hundreth

so your final answer is 9.42

Answer:1

Step-by-step explanation:

Answer:

The easiest way to figure this is to find P(no girls in 5 births) = (1/2)^5 = 1/32 -------------- The P(at least one girl in 5 births) = 1 - 1/32 = 31/32

The probability that when they have five children, at least one of them is a boy is 31/32

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome:

The probability that a couple will have a boy or girl among the five children = 1/2

If they gave birth to 5 children:

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)^n where:

n is the total number of children

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)ⁿ

The probability that when they have five children, at least one of them is a boy = 1 - (1/2)⁵

The probability that when they have five children, at least one of them is a boy = 1- 1/32 = 31/32

Hence the probability that when they have five children, at least one of them is a boy is 31/32

Answer:

The population mean

Normally distributed

Please give me brainliest, I really need it.

a)As the number of surveys increases, the mean of the sample means will approach the population mean.

b)Means will be normally distributed.

A normal distribution is a probability distribution that is symmetric about the mean, and data near the mean are more frequent than data far from the mean.

As the number of surveys increases, we will have more data.

So, the mean of the sample means will approach the population mean.

Means will be normally distributed because each survey has the same number of respondents.

Thus, a)as the number of surveys increases, the mean of the sample means will approach the population mean.

b)Means will be normally distributed.

Answer:

y = -3x + 5

Step-by-step explanation:

Since the y-intercept occurs at the point (0,5), you can use that and the point slope equation to find the equation.

This looks like y - 5 = -3 (x - 0);

Solving for y, you get y = -3x + 5;

To graph this equation you would put one point at (0,5), then use the slope to count down three and to the left one to find other points, or you could just plug in numbers for x to find their corresponding y values and plot it like that.

Hopefully this helps- let me know if you have any questions!
